The recruitment mission will add them to the squad for you to deploy as you see fit, while their loyalty mission will increase their competence both in storyline and in actual gameplay. Squadmates typically have two missions associated with them: their recruitment mission, and their loyalty mission.

We choose the Guardian variant for the better Power recharge, and slightly increased health. We max out Defender to get all those Health and Cooldown passives allowing you to take more hits, and cast more powers. It’s worth noting that the other variant is arguably better for this build as it takes away the second shield Assault gives you, but it’ll increase your Biotic Damage by 15% and your shield strength to 100%. Furthermore, Tech Armor doesn’t need to be reapplied, just put it on at the beginning of a Mission, and it’ll stay on indefinitely until it gets destroyed. At max rank, it’ll increase your shields up to 100% of your base shield value, although it doesn’t take account of your armor increasing your shield strength, Assault Armor will replenish 50% of them when your shield is destroyed which is the reason we went with this variant of the Power. Tech Armor is a unique Tech power exclusive to Sentinels. We choose the Heavy Warp Evolved variant as this increases the damage to Warp allowing you to do increased damage to Armor. Warp is great to use against enemies that have Barriers or Armor, and on top of that, it can stop health regeneration as well. We choose the Heavy Overload Evolved variant as this increases the damage to Overload allowing you to do take the enemies shields down even quicker.

Overload is the de facto Power to use when you want to strip the enemies of their shields.

This section will go into more detail on why the Powers are chosen for this particular build.
